REVERSIBLE' DRAFT.

Specication of Letters Patent.

Patented Apr. 30, 1912.

Application filed September 30, 1911. Seria1 No. 652,094.

To all 'whom t may @Oncern Be it known that I, MURRAY B. METCALF, acitizen of the United St-ates, residing at Cowanesque, in the county ofTioga and State of Pennsylvania, have invented new and usefulImprovements in Reversible Drafts, of which the following is aspecification.

This invention relates to reversible draft mechanism for harrows, gangplows or other agricultural instruments to enable the same to be workedupon hill sides without interfering with the work of the instrument orexert-ing undue labor to the animals attached to the instrument.

With the above objects, and others of a similar nature in view, theinvention resides in the novel construction, combination and arrangementof parts set forth in and falling within the scope of the appendedclaims.

In the drawings,-Figure 1 is a top plan view of the improvement attachedto a harrow, showing the draft in one posit-ion. Fig. 2 is a similarview showing the draft attaching member being moved to anotherposit-ion. Fig. 3 is a horizontal sectional view of the same. Fig. t isa plan view of the frame.

Referring to the accompanying drawings, in which like referencecharacters designate corresponding parts throughout, the numeral ldesignates, in diagram, a harrow of the ordinary construction.

Secured to the harrow is a substantially U-shaped frame 2, thelongitudinal or connecting member of the said frame having its innerface provided with a plurality of notches 3, while the side arms of theframe are attached to the harrow. The notches 3 may be given indicatingcharacters to designate the distance of the throw of a yoke withrelation to the central notch, as will hereinafter be more fully setforth.

The connecting member of the frame is provided with suitable studs 4,the same securing a cross bar 5. The studs 4 each pivotally connect asubstantially curved lever wit-h the frame. The space between the frame,the levers and the connect-ing bar is provided with suitable washers,and the levers, as illustrated in the drawings, cross each other andhave their free ends provided with openings for the reception ofsuitable cords, cables or the like whereby one or both of the saidlevers may be swung upon its pivot.

The central depression of the frame is preferably rectangular, andenlarged, while the remaining depressions are substantially V-shaped,and adapted to be engaged within any of the said depressions is a yoke10 which carries upon its outer end a ring 1l to which the swingle ordouble tree is att-ached. The yoke, of course, is contacted by thelevers, and it will be noted that a pull upon the cord`d or cableattached to either one of the levers will draw the connecting member ofthe yoke out of its depression and direct it to any one of the remainingdepressions of the frame, so that the line of draft is thus changedwithout the occupant of the farming implement leaving his seat, it beingunderstood that the ropes or cables are of a suiiicient length to beattached to the implement and readily accessible to the driver.

Having thus described the invention, what I claim is 1. In a device forthe purpose set forth, a notched frame, curved levers pivotallyconnected to the opposite ends of the frame, a yoke adapted to engageone of the notches and to be contacted by one or both of the levers, andflexible elements secured to the levers for swinging the yoke out of oneof the notches and into the direction of any of the opposite notches.

2. In a device for the purpose set forth, the combination with aU-shaped frame, the connecting member of t-he frame having its innerface notched, studs upon the opposite ends of the connecting members, aninwardly curved arm pivotally connected with each of the studs, aconnecting bar for the studs, a substantially U-shaped yoke surroundingthe connecting bar, the frame and the levers, said yoke adapted toengage within one of the notches, and flexible elements connected withthe levers for swinging t-he yoke out of the notch and directing theyoke toward any of the remaining notches.

In testimony whereof I affix my signaturev in presence of two witnesses.
